I could be wrong here but I don't think it was Wonder Pig that bumped Batmite. I think it was yet another (*sigh*)Batman w/Batarang single. We got 2 pretty close together. I think Wonder Pig came out the year before.

Can we start pestering Toy Guru for a Signal Man/Starfire/Cyborg Superman 3-pack now?

I'd buy that 3 pack in a millisecond. I'm sure if they are smart enough they'll release Starfire and Cyborg in the Young Justice line. They could easily introduce them in future seasons and they surely know that fans want small animated scale figures of them. Not sure about Signal Man. I love obscure villains so I'm all in for whatever figure of him, but his chances are very slim unless he appears in a future Young Justice episode. Let's just hope and cross our fingers. Toyguru said the last 6 3 packs are the last JLU so my hopes for these three figures are pretty small.

Well before we all get carried away we don't even know if they made it to the prototype stages and that's assuming Mattel actually had any plans of making these characters in the first place.

I wouldn't have minded seeing these 3 in the long run. Of the 3 Starfire was the only one that ever made it on one of my top ten want lists. So although they would have been nice I can live without Signal Man and Cyborg Superman. If I would have had to choose between 2 figures that we did get getting made and those 2 I would have probably passed on Signal Man and Cyborg Superman.
